Conclusion to Our React Currency Converter App

This final module wraps up your Currency Converter App project. You’ll reflect on what you learned, test your knowledge with a short quiz, view the live app, and explore resources to continue your React journey.

By building this Currency Converter step by step, you’ve developed hands-on experience with modern React development. Let’s recap what you’ve achieved:

1. Set up a React project with Vite
   • You used Vite for fast development, instant hot-reloading, and a smooth developer experience.
2. Built a Currency Converter UI
   • Designed a clean interface with an input field, dropdowns for currency selection, and a result display.
   • Used Tailwind CSS to make it responsive and modern.
3. Managed State with React Hooks
   • Used useState to track the amount, base currency, and target currency.
   • Used useEffect to fetch and update exchange rates whenever inputs changed.
4. Fetched Live Exchange Rates
   • Integrated with a free currency API (like exchangerate.host) using fetch.
   • Handled asynchronous data and displayed conversion results dynamically.
5. Added Core Functionality
   • Conversion updates instantly when users change amount or currency.
   • Default values ensure the app works right away without extra input.
6. Styled the App with Tailwind CSS
   • Responsive layout works on both mobile and desktop.
   • Used utility classes for spacing, typography, and modern styling.
7. Organized Files & Components
   • Clear src/ folder with components like CurrencyConverter.jsx.
   • Kept logic and presentation structured for readability.
8. Deployed with Netlify
   • You learned how to build (npm run build), connect GitHub, and deploy live on Netlify.
   • Your app is now accessible worldwide with a shareable link.

1. Which React hook is used to store the user’s input and selected currencies?
   a) useRef
   b) useState
   c) useMemo
   d) useReducer
2. What is the purpose of useEffect in the app?
   a) To change styling dynamically
   b) To fetch exchange rates whenever dependencies change
   c) To store form input values
   d) To add animations
3. How do we fetch exchange rates from the API?
   a) With axios.get
   b) By importing a JSON file
   c) Using the fetch() function
   d) By hardcoding values
4. What happens if the API call fails?
   a) The app stops working completely
   b) You can add error handling (like a fallback message)
   c) Conversion happens with old values
   d) Nothing changes
5. Why did we use Vite instead of Create React App?
   a) It looks cooler
   b) Vite has faster builds and hot reload
   c) CRA doesn’t support Tailwind
   d) Vite automatically deploys to Netlify

Answer Key

1 → b (useState stores input and selected currencies)
2 → b (useEffect triggers API fetch when values change)
3 → c (fetch() is used to get rates from the API)
4 → b (error handling ensures the UI doesn’t break)
5 → b (Vite is faster and more modern than CRA)
